Steps taken: Load up bare metal or a VM with FC16 Install 3.0 from http://www.ovirt.org/releases/stable/fedora/16/ Setup up something minimal (EG: engine-setup then setup a basic datacenter/cluster/etc) Add a FC16 or EL based node for fun as well and some VM's if feeling ambitious. Back up database: systemctl stop jboss-as.service pg_dump -C -E UTF8 --column-inserts --disable-dollar-quoting --disable-triggers -U postgres --format=p -f "/temp/engine.sql" engine Back up the following files within /etc/pki/ovirt-engine from a 3.0 install (preserve owner/group). /etc/pki/ovirt-engine/cacert.conf /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/cert.conf /etc/pki/ovirt-engine/certs/01.pem /etc/pki/ovirt-engine/certs/02.pem /etc/pki/ovirt-engine/certs/ca.der /etc/pki/ovirt-engine/certs/engine.cer /etc/pki/ovirt-engine/certs/engine.der /etc/pki/ovirt-engine/database.txt /etc/pki/ovirt-engine/database.txt.attr /etc/pki/ovirt-engine/database.txt.attr.old /etc/pki/ovirt-engine/database.txt.old /etc/pki/ovirt-engine/keys/engine_id_rsa /etc/pki/ovirt-engine/keys/engine.ssh.key.txt /etc/pki/ovirt-engine/private/ca.pem /etc/pki/ovirt-engine/requests/ca.csr /etc/pki/ovirt-engine/requests/engine.req Load up bare metal or a VM with FC17 (Upgrade from FC16 --> FC17 is still rather messy) Install 3.1 from http://www.ovirt.org/releases/beta/fedora/17/ Run engine-setup to get an initial setup. stop ovirt-engine (systemctl stop ovirt-engine.service) Copy the previously backed up /etc/pki/ovirt-engine files from above over top of the ones just generated (be sure to preserve owner/group EG: cp -a) Drop the existing engine database: dropdb -U postgres engine Create a new blank database: createdb -U postgres engine Populate with with the backup of the above 3.0 database: psql -U postgres -d engine -w < "/temp/engine.sql" Attempt to upgrade the DBschema via /usr/share/ovirt-engine/dbscripts/upgrade.sh upgrade.sh -u postgres The DB schema upgrade will fail like so: Running upgrade script upgrade/03_01_0260_add_job_table.sql psql:upgrade/03_01_0260_add_job_table.sql:29: NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "pk_jobs" for table "job" CONTEXT: SQL statement "CREATE TABLE job ( job_id UUID NOT NULL, action_type VARCHAR(50) NOT NULL, description TEXT NOT NULL, status VARCHAR(32) NOT NULL, owner_id UUID, visible BOOLEAN NOT NULL DEFAULT true, start_time TIMESTAMP WITH TIME ZONE NOT NULL, end_time TIMESTAMP WITH TIME ZONE default NULL, last_update_time TIMESTAMP WITH TIME ZONE default NULL, correlation_id VARCHAR(50) NOT NULL, CONSTRAINT pk_jobs PRIMARY KEY(job_id) ) WITH OIDS" PL/pgSQL function "__temp_upgrade_add_job_table" line 6 at SQL statement psql:/tmp/tmp.mXz8U4xpWr:3: ERROR: column "comment" of relation "schema_version" does not exist LINE 1: ...ksum,installed_by,started_at,ended_at,state,current,comment) My assumption here is that if the DB schema upgrade would work, that this should be the cleanest way to upgrade from 3.0 to 3.1. - DHC
